A valuable addition
I never look at the moon without using a moon filter, it's just too bright otherwise and I find it hurts your eyes, especially when there's a full moon and it is exceptionally bright. More detail can be seen using this filter as it takes away that dazzling brightness that hinders observation.

If you haven't got a moon filter already you should look at investing in one as they aren't particularly expensive (in comparision to most other astronomy accessories!).

luner filter
this is a great bit of kit if you wont to start looking at the stars then you need this it takes all the glare out and brings up the deffinition with out it the moon is a very bright ball with a few visable marks with the filter you can see all the craters and land marks if you have a telescope then you need this even if you dont wont to buy any more lens you need to buy this filter.great for taking the glare off stars as well possible use when bird or long distance viewing as well best buy ever ********** buy one today!

It works good
The moon filter is a small attachment as you will imagin being made to fit a 1" + 1/4" lens. I am a compleat beginer so didn't know the filter screwed on to the bottom of the lens that being the shiny bit that goes into the telescope. So for a while it was sitting on top of the lens falling onto the floor every time I touched the eye piece, in the dark and behind the flower pot, I always managed to find it gave me new confidence in my night vision. I explained this to my seller he said what to do but I still didn't get it, till an experienced astronomer at the astro club had to show me, and assured me that it wouldn't fall into the telescope, and thats how you fit the other filters. Celestron Moon Filter Mine is, and I can recomend the £3.99 one and it is good.
